UNITED STATES PATENT FFICE.l

ABEL BREAER, OF SAUGATUCK, CONNECTICUT.

LUBRICATOR.

Specification of Letters Patent No. 14,797, dated May 6, 1856.

To all 'whomt may concern Be it known that I, ABEL BREAER, of Saugatuck, in the county of Fairfield and State of Connecticut, have invented a new and useful Improvement in Grease-Cocks; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, forming part of this specification, Which represents a central vertical section of a grease-cock with my improvement.

This invention consists in the attachment of a syringe directly Vto the plug of the cock, so that by turning the plug in one position I am enabled to charge the syringe with grease from the reservoir or grease cup, and by afterward changing the position of the plug, I am enabled to discharge the contents of the syringe against a pressure of steam into the cylinder, or steam chest or other part of the engine to Which the cock may be applied. By this method of applying the syringe to the cock, an exceedingly simple apparatus is obtained.

To enable others to make and use my invention, I will proceed to describe its construction and operation.

A, is the socket or plug seat of the cock, Which is of Well-known form.

B, is the grease cup or reservoir attached to the top of the socket, A.

C, is the plug of the cock having the cylinder, D, of the syringe cast on or other- Wise attached to one end.

a, is a passage leading direct from the cylinder, I), into the middle of the plug, (J.

b, is a passage leading from the passage, a, through one side of the plug. C, so as to be capable of communicating either With the passage, c, in the socket, A, Which leads to the grease cup or reservoir, or with the discharge passage, cZ.

E, is the plunger of the syringe.

F, is a handle to turn the plug, C.

The operation of the cock is by first turning the plug, C, to bring the passage, 7), opposite the passage, c, then drawing the plunger outward Which fills the cylinder, D, next turning the plug to bring the passage, Z), opposite the passage, (Z, and after- Ward the plunger inward toward the plug., C, Which forces the contents fromthe cylinder, D, through the passage, (l.

I do not claim the application of a piston or syringe to a grease cock to force the grease against a pressure of steam; but

IV hat I claim as my invention and desire to secure by Letters Patent, is

The attachment of the syringe directly to the plug of the cock, substantially as herein described.

ABEL BREAER.
